Analyze the following code:

public class Test {
  public static void main(String[] args) {
xMethod(5, 500L);
  }

  public static void xMethod(int n, long l) {
    System.out.println("int, long");
  }

  public static void xMethod(long n, long l) {
    System.out.println("long, long");
  }
}

Group of answer choices

The program prints 2 lines: int, long long, long

The program contains a compile error because Java can't tell which method to invoke.

The program prints long, long

The program prints int, long

Solutions

Expert Solution

The Correct Answer is Choice 4 which is

The program prints int, long

Explaination :

The program prints 2 lines: int, long long, long

This option is not correct because we are calling xMethod by passing integer and long (5 , 500L) values so it will call xMethod(int n, long l) and this method print only 1 line that is int , long

-----------------------

The program contains a compile error because Java can't tell which method to invoke.

This is not correct because in java compiler automatically find out which method has been called based on argument passed in overloading methods .

--------------------------

The program prints long, long

This option is not correct because we are calling xMethod by passing integer and long (5 , 500L) values so it will call xMethod(int n, long l) and this method print only 1 line that is int , long . If we passed (5L,500L) then this method xMethod(long n, long l) should be called by compiler

---------------------

The program prints int, long

This option is correct because we are calling xMethod by passing integer and long (5 , 500L) values so it will call xMethod(int n, long l) and this method print only 1 line that is int , long
